Seepage velocity as a function of correlation length (), Minkowski functionals—porosity (φ), specific surface area (SSA), mean curvature (MC), and Euler number ()—and literature relationships for effective diffusivity, , , and , respectively, for generated porous media (black triangles and blue circles for exponential (EXX) and Gaussian (GXX) variogram models, respectively) and scanned sandpacks (SP) (red squares). The coefficient of determination () associated with the fitting functions for the SSA and MC (red lines) is reported in (c, d).
